To all whom it may concern:

Be it known that 1, ROBERT of the borough of Brooklyn, county 'of Kings, city and State of New York, have inventedwrtain new and useful Improvements in Demountable Rims for Vehicle- Wheels, of which the following is a specification, accompanied by drawings.

This invention relates to demountable rims for vehicle wheels, more especially for motor vehicles.

In the usual demountable rim, as now constructed, each clamping lug must be unclamped in locked position at once.

igw inafter appear and I bolted to remove the rim and separately adjusted and tightened in position when the rim is replaced. A certain amount of time is consumed in these operations and one objects]? my invention is to avoid the necessity of separately tightening each lug and thus simplify the operations necessary in demounting and mounting the rim when changing tires.

In accordance clamping lugs are all with my invention, the released at once or I acoomplish this object by means of a circumierentially shiftable continuous locking ring mounted at the side of the felly outside or in front of the clamping lugs.

l Instead of the usual bolts and nuts for each clamping lug, the lugs are mounted on studs and the locking ring may be provided with openings corresponding to the lugs.

By turning the locking ring until the openings are opposite the lugs, the lugs may be loosened and the rim removed. When the .lugs are readjusted in position, the look-- ing ring is shifted circumferentially' to bring the solid portions of the ring opposite the lugs and lock them in position. Means are also provided for securing the locking ring in locked position. Various means may be provided for carrying out this general principle of operation. The lugs maya'be either separate and independent or they may form an integral portion of the rim itself. The lugs may also be connected to a ring or otherwise connected together, so. that' they may all be removed or replaced at the same time. Different forms of locking rings may be provided and if desired, the locking ring itself may be removably mountedat the side of the wheel felly.

Further objects of the invention will herehave illustrated the G. MASON, a citizen of the United States, and a resident preferred forms of the invention, in the accompanying drawings, in which:

Referring to the drawings, and more particular] y to the form of the invention shown in Figs. 1 to 7 inclusive, A represents a pneumatic tire carried by the demountable rim B which is shown mounted on the usual felly plate E on the folly E. The rim is adapted to be held in place by the usual lugs C independent of the rim and loosely mounted, in this instance, on the studs D carried by the folly. Bearing plates 1) are preferably provided underneath the lugs. It will be observed that the studs 1) do not project beyond the outer faces of the lugs and said outer faces are preferably transversely corrugated at 0 for a purpose to hereinafter appear, although the corrugations may be omitted, if desired. v

Outside or in'front of the lugs C is mounted a locking ring F and this locking ring is preferably provided with openings (i correspending in number to the lugs C. The locking ring F is so mounted that it may be shifted circumferentially to bring the openings (i opposite the lugs C, as shown in Figs. 2 and 7, to unlock or release the lugs and permit the rim 1) to be removed. By shifting the locking ring F in the opposite direction, solid portions of the ring are brought opposite the lugs C to lock them in clamping position. The locking ring is preferably provided with Wedge shaped bearing portions ll adjacent the OPQIllIlQ'S G, and these bearing portions are preferably corrugated, as at l, to cooperate with the corrugations on the lugs and prevent radial movement and rattling of the lugs.

Suitable means for slidably mounting the locking ring, consist of bolts J extending through the folly l) and projecting through slots ll .in the looking ring. 'lhese bolls J are provided with the nuts K andvmay be tightened to a suliieient degree to permit a sliding movement of the locking ring.

The locking ring is also preferal'ily provided with the outer and inner flanges F and F extending inwardly toward the telly to prevent dust and dirt from accumulating between the telly and the ring. The

outer flange F is preferably cut away at F- to permit the sliding movement of the ring.

In order to provide means for covering the openings (i-when the parts are in locked po-v sition, as shown in Figs. 1 and 4:, a protective ring or shield Q of light metal, circumferentially slidable independently of the locking ring F, is provided. This outer shield is provided with slots S somewhat longer than the slots H in the locking ring, and the bolts J project through the slots S. The shield Q is provided with the openings it corresponding in number to the openings still farther in the same direction, in order to bring solid portions of the shield opposite the openings (2 in the locking ring a'ndthus cover said openings.

Suitable means are provided for securing or holding the locking ring F and shield Q in locked position. For this purpose a'n ad ditional bolt T is provided in the folly adapted to be passed through registering holes in the ring F and shield Q and then tightened in position by means of the nut '.l".,- The locking ring F is'preferably provided with an interiorly screw threaded boss or enlargement F asshown in Fig. 6, to receive theserew threaded end of the bolt T.

Let it be assumed that the rim is to be 'demounted and that the parts are in locked position, as shown in Fig. 1. The securing bolt T would first be removed or withdrawn sufficiently to permit the locking ring 'and shield Q to be shifted into the position.

shown in Figs. 2 and 7, with the respective openings in said ring and shield opposite the lugs (I. The lugs may then be loosened or removed and the rim B removed. After having replaced the rim the logs are adjusted on their studs 1), the ring and shield are shifted to locking position and the securing bolt T is readjusted and tightened, and the wheel is ready for use. 1

In the form of the invention shown in Figs. 8 to 12, a modification of the outer protective shieldv is illustrated, which is so constructed that it may be shifted to cover not only the openings (2 in the locking ring F, but also the'slots ll in the locking ring when the parts are in locked position. This feature is an advantage under some circumstances, in order to prevent mud or dirt from accumulating in the slots ll in the looking ring. In this modification the outer shield is also provided with an outer flange F for covering the openings or gaps over the openings G in the locking ring F.

Figs. 8, 9 and. 10 illustrate three positions of the looking ring F and outer shield-Q. The shield Q is provided with slots S sulostantially equal in length to the slots H in In Fig. 8 the parts are shown in unlocked position with the openings R and G in the shield and ring respectivel opposite the lugs C and the outer flange of the shield Q, corresponds to the outer flange F of the ring 5. In the position of the parts shown in Fig. 9, both thc ring F and the shield Q, have been moved together to bring the Wedge shaped bearing portions L opposite the lugsC and the'slots H and openings G in the ring F remain uncovered. In Fig. 10 the shield Q, has been moved back in the opposite direction to bring solid. portions the shield opposite the openings G in slots iii in the ring F, and solid portions of the nter flange F of the shield Q are broughtover the openings G in the ring F.

Fig, 11 shown with parts in locked position and the slots and openings G covered by the shield Q. The modified construction described is best illustrated in Fig. 12, a perspective View, showing how mud and dirt are prevented from accumulating in any portions of'the rim construction.

In Figs. 1?. to 16 inclusive, the lugs G are shown connected by a ring U so that they may all be removed or replaced at the same time. Otherwise the rim construction is like that shown in Figs. to 7 inclusive. A detail view of the lugs C connected by the ring U is shown in Fig. 13, and in Fig. 14: a side view of a wheel is shown with the lugs in position and before the locking ring and shield Q have been adjusted.

In Figs. 17 to 21 inclusive 2. modified form of construction is shown in which the lugs C are formed integral with the demountable rim BC In this modification the locking ring V is removably mounted onthe folly outside the lugs G and is provided with wedge shaped bearing portions L and the flanges F and'F The openings in ffhe ring V, are omitted in this modification, and the ring is solid throughout, except for the slots W, which are provided with enlarged ends X, in order to permit the slots to be placed over the bolts Y. The ring V is then shifted circumferentially to bring the wedge-shaped bearing portions L opposite the lugs G and the ring is secured in position by means of the securing bolt Z. in order to remove the rim B, the securing bolt Z is removed, the ring V is shifted until the bolts Y lie in the enlarged portions K of the slots W and the entire ring V is removed, which permits the rim B to be removed.

"it is to be understood that in the modification shown in Figs. 17 to 9.1, with the lugs C integral with the rim B, a locking ring and shield with openings corresponding to the lugs could be used as described a side view of the wheel is in connection with the other figures, and

obviously in Figs.v 17 to 21 could be used with the separate lugs, as shown in the other figures.

One of the important features of my invention resides in the fact that my improved locking means for the lugs of a demountable rim may be applied to existing'constructions, already on vehicle wheels. It is only necessary to remove the projecting portions of the lug bolts, so that my locking ring may bear directly upon the lugs. The

bolts for the sliding locking ring may be inserted at proper intervals in the folly of the wheel, and it"is not necessary to otherwise alter the rim construction. The cost of equipping vehicle Wheels with my improvement is therefore brought to a low figure, because especially formed wheels and rims with complicated parts are not necessarv.
